Thank you for your swift response.Regardless of your wife following you or not you still have to show funds for all your family members depending on how large it is.... If it's just 2 of you then you'll show funds for 2 and if you have kids you'll add them to it as well... If they're following or not.
As regards increasing your scores best you retake your ielts and also include your spouse own too... Her ECA and ielts as well.
All the best.
However, I have read that applying as a single applicant gives more points than applying as a married applicant. I will look for the link and post it here
